Product Description:
The T404-012 is a DC brush servo motor assembled by Sanyo Denki for the T SANMOTION Servo Motors series. This compact unit delivers precise rotary motion for positioning axes in industrial automation equipment by converting command current into mechanical rotation through its armature circuit. Built around a 41 mm square flange, it integrates easily into light-duty pick-and-place heads, small conveyors, and laboratory devices that require repeatable torque delivery. Its compact form also allows installation in machinery with limited space around the driven axis.
The motor supplies a continuous stall torque of 0.14 N·m, allowing it to hold a load without overheating when the shaft is locked. Under rated conditions, it generates 0.04 kW of mechanical power at a shaft speed of 3000 rpm, a combination suited to miniature gear stages and direct-drive couplings. The armature is energized by 72 V DC, so the drive amplifier must provide a matching bus with low ripple to support smooth rotation. The IP43 enclosure provides basic protection against solid objects and spraying water. A lead-wire connection reduces the space required for electrical connections, while the D-shaped output shaft provides positive engagement with compatible couplings. No oil seal is fitted, so the machine interface must provide external sealing when protection against oil is required. The motor does not include a tachometer generator, leaving speed feedback to an external encoder or another compatible feedback device.
The motor provides a peak stall torque of 0.76 N·m for brief transients such as rapid indexing moves. Acceleration response is aided by a rotor inertia of 0.084 × 10⁻⁴ kg·m², allowing responsive speed changes without placing excessive inertial demand on the servo system. The frame weighs 0.4 kg, which reduces the load carried by small linear slides and permits the use of compact support structures. The integral leads extend 1000 mm, providing sufficient reach for routing inside compact panels while reducing the need for additional junctions. The low rotor inertia supports quick reversals in applications that require frequent starts and stops. The combination of a compact flange and long integral leads also simplifies placement when the amplifier is mounted away from the motor.
